Method Detail

withConnectorConfiguration

public DebeziumIO.Read<T> withConnectorConfiguration(DebeziumIO.ConnectorConfiguration config)

Applies the given configuration to the connector. It cannot be null.

Parameters:

config - Configuration to be used within the connector.

Returns:

PTransform DebeziumIO.read()

withFormatFunction

public DebeziumIO.Read<T> withFormatFunction(SourceRecordMapper<T> mapperFn)

Applies a SourceRecordMapper to the connector. It cannot be null.

Parameters:

mapperFn - the mapper function to be used on each SourceRecord.

Returns:

PTransform DebeziumIO.read()

withCoder

public DebeziumIO.Read<T> withCoder(org.apache.beam.sdk.coders.Coder<T> coder)

Applies a Coder to the connector. It cannot be null

Parameters:

coder - The Coder to be used over the data.

Returns:

PTransform DebeziumIO.read()

withMaxNumberOfRecords

public DebeziumIO.Read<T> withMaxNumberOfRecords(java.lang.Integer maxNumberOfRecords)

Once the specified number of records has been reached, it will stop fetching them. The value can be null (default) which means it will not stop.

Parameters:

maxNumberOfRecords - The maximum number of records to be fetched before stop.

Returns:

PTransform DebeziumIO.read()
